I Specification of Letters Patent. Application filed March 13, 1912.Serial nopes'asia Patented Dec.24,11912.

To all'whom it may concern: I

Be it known that I, WILLIAM J ."KENELY, a citizen of the United States,residing at Elizabeth, in the county of Union andState ofNew Jersey,have invented certain Improvements in Stovepipe-Hoods,of which p thefollowing is a specification.

The objects ofthe invention are to provide animproved hood for gatheringthe jrising vapors, odors and the like and defleeting the same from acook stove into the *stovepipe; to provide suitablemeans of es-- capefor such vapors, which shall not interfere with the draft or efficientoperation of the stove; to provide means forclosing the vent, whichmeans shall be readily operated, to secure a rigid but detachable hood;to segcure simplicity of construction and'installfment, andto obtainother advantages and ing description.

results as may be brought out in the followqReferr'ing to theaccompanying drawings,

,in which like numerals of reference. indicate the same parts.throughout the several views, Figure 1 is a sideelevation of my deviceapplied to a length of stove pipe, parts of the hood being broken awayfor the better disclosure ofthe invention;Fig. 2 is a I. 1 plan view ofthe sameyFig. S is a'vertical section on line AA of Fig. 2; Fig. 4 is afront elevation with the hood removed, and

Fig. 5 is a cross-sectional view on 1ineB-B of Fig. 4, looking in thedirection indicated by the arrows. I I

In the specific embodiment ofthe invention illustrated in said drawings,1 designates a length of stovepipe to'whi'ch the invention is applied.As the principal application of the invention is to any stovepipeleadingfrom the ordinary kitchen range to the chimney. proper,,it isevident that the I invention is not restricted to a pipe of circularcross section, such as shown in the drawings, but is applicable to thevarious sizes and shapes of pipe in use.

.Circumferentially of'the pipe, and extending approximately halfwayaround the same, is a strap of sheet-metal 2, held thereto by rivets 3near each end,'or otherequivalent means, The major portion of the strap2 is offset, as ate, to provide a slot 5 between the strap and the pipe.The pipe is p red as at 6, said aperture commenc ng between the pper andlower-edges of "the strap 2, preferably, and extending downward'for somedistance below said strap.

The sheet-metal at eachof the vertical edgesof'this aperture is'doubledback as at u 7, see Fig. 5, and then returned forward againsubstantially parallel to itself in spaced relation thereto,: as at 71,forming; thereby a slideway 8 between theportions 7 and 71 mentioned.The slideways 8 thus I extend slightly under the strap 2, and areprevented from undue expansion or inadvertent distortion by engagementwith the said strap.

. Slidably'mounted within the above'men tionedslideways 8, is aslide orvent regulator 9, preferably constructed of sheet metal similar to thatof which the pipe is composed, and curved transversely of itselfconcentric therewith. A stop 10. is stamped from, and bent outwardlyperpendicular to the. slide 9, preferablyfcentral of the lower edge, sothat when thefslide is raised or opened, the stop 10 .engages thestrap2,

thereby limiting the upward movement of the slide. The material of whichthe slide is "composed is bent outwardly, above the strap 2, and thenbent upwardly again at 12 with reduced 'widthof metal to form a handle,the upper extremity of such handle 12 being provided with an outwardlyprojecting finger-piece 13 suitablefor the man ualcontrol and operationof the slide. jThe outwardly bent portion 11 forms a shoulder or stop tolimit the downward movement of the slide 9, and at the same time itpositions-the handle 12 away from the pipel so as tobe ireadilyoperable. In the absence of the hood next to be described, this shoulderengages the upper edge of the strap 2 whereby furtherdisplacementdownwardly is prevented. The hood, of above made, 'comprisesessentially a fanwhich' cursory mention is shaped metallic top 14, thediverging edges 15 of which are approximatelyin radial planes of thestove pipe 1, when operatively assembled. The outer edge 16 ispreferably arcuate, making the top 14 thereby alsegment of a circle. Theinneror vertex end of such top is cut away upon a circular line 17 toregister with the inner edge of the strap 2. Preferably attheintersection of such arcuate line 17 and the radial sideedges15,

are secured as by rivets;.18, angular pieces or hooks 19 which benddownwardly and are adapted to take into the slot 5 to removably supportthe hood and retain the same against lateral displacement.

Preferably integral with the top 1 1 of the hood are its depending andpreferably plane sides 20, 20, of triangular shape with one vertexregistering with the point of intersection of the outer arcuate edge 16and the respective radial edge 15 of the top. The inner edges 21 of suchtriangular-1y shaped sides 20 are substantially vertical, as shown bestin Fig. 1, and adapted to meet and en gage the cylindrical surface ofthe pipe 1 along longitudinal elements thereof.

A segmental collar 22 inwardly connects the lower, inner vertices of thesides 20, being attached thereto by rivets 23 or the like. This collaris curved to engage the convex surface of the pipe when in operativeposition, and the moment of inertia introduced by the weight of the hoodtends to rotate the same about the angular pieces or hooks 19 as anaxis, such moment being balanced into stable and static equilibrium bythe reaction of the strip 22 bearing against the pipe, thereby holdingthe hood in position. The triangular shape and arrangement of the sidesinclines the top 14. downwardly as it projects outwardly by virtue ofwhich rising vapors will be deflected inwardly upon being intercepted bythe hood.

lVhen the hood is in operative position, the shoulder 11 of the slide 9engages the inner edge of the hood top as shown in Fig. 3.

The removal of the hood is efi'ected by first sufticientlv raising theslide to disengage the hood; then lifting the hood, the hooks 19disengage the strap 2, and the hood can be removed entirely from thepipe.

The operation of the device is evident and self explanatory. The hotgases, odors, and so forth which rise from the stove are intercepted bythe hood and deflected inwardly as already stated. \Vith the slide 9open, the gases pass on into and up the stovepipe. The presence andprobably the inclination of the hood prevents the down draft of cold airinto the stovepipe which would interfere with the draft of the stove.The slide is provided for use when it is desired to regulate or closethe vent into the pipe, and more especially when it is desired to removethe hood entirely. It may here be stated that the action of the gases asabove stated produces an inward current which will draw into the stovepipe other gases than those which would normally use and be interceptedby the hood.

In order to insure sufficient frictional engagement of the slide 9 withthe slideways 8, I double back the edges 24- of the slide designed toslide therein, as shown in Fig. 5. The. expansive tendency of suchstructure retains the slide in frictional engagement with the slideways,as desired, and if in the course of time the expansive tendency maydecrease, the doubled-over portion may be spread again with any suitabletool.

Having thus described the invention, what Iclaim is:

1. The combination with a pipe having a lateral aperture, of a strapmounted on the outside of said pipe adjacent to said aperture having aportion at right angles to the length of the pipe and spaced therefrom,a slide for said aperture working between said strap and pipe, and. ahood having hooks adapted to detachably take into the slot between saidstrap and pipe on opposite sides of said slide.

2. The combination with a pipe having a lateral aperture, of a strapmounted upon the outside of said pipe with a portion extending at rightangles to the length of the pipe and spaced therefrom, a hood having atop and depending sides, hooks at the upper edges of the sides of saidhood adapted to take into the slot between said strap and the pipe, anda strip connecting the lower edges of said sides of the hood and adaptedto engage the pipe.

4.
